Matt Cherette · 08/19/11 03:40AMPhoenix, Arizona was enveloped by a giant dust storm on Thursday afternoon, marking the third time a haboob has hit the city in two months. The wall of dust caused the city's sky to turn brown, its power lines to fall down, and its transportation systems to slow to a halt.
